What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFever in cancer patients can occur for reasons other than bacterial infections. Without practical tools to distinguish actual infections, treatment delays may occur, reducing effectiveness and increasing antibiotic resistance. This study aimed to identify clinical features and procalcitonin (PCT) levels as indicators of bacterial infection in fevers among cancer patients.
methodsThis retrospective study enrolled 225 patients with cancer and fever at the Maharat Nakhon Ratchasima Hospital. Data on the clinical characteristics, laboratory results, and bacterial cultures were collected. Associations were analyzed using logistic regression, and the appropriate PCT cutoff point was determined using ROC analysis.
resultsOf 225 cancer patients with fever, 54 (24%) had positive bacterial cultures, with Klebsiella pneumoniae being the most common pathogen. Significant clinical features included age (OR 1.06, 95% CI 1.01-1.12), increased heart rate (OR 1.05, 95% CI 1.02-1.08), and localizing symptoms (OR 7.62, 95% CI 2.49-22.70). Key laboratory findings were absolute neutrophil count (OR 1.15, 95% CI 1.03-1.28) and PCT level (OR 1.39, 95% CI 1.07-1.80). Appropriate PCT cutoff points for predicting bacterial infection were analyzed using various methods, resulting in values of 1.045, 0.546, 0.546, and 0.4025 ng/ml. The concordance probability and closest to the point (0,1) methods suggested a rounded cutoff point of 0.5 ng/ml, which provided a sensitivity of 61% and a specificity of 78%. The AUC for PCT was 0.731, indicating moderate accuracy.
conclusionProcalcitonin, in conjunction with clinical features, may be used to classify the cause of fever in cancer patients. Therefore, a clinically predictive model would be useful.
